Abstract
A digital video camera performs a method to improve the image quality of captured images in a video image stream. The method includes capturing a first subset of images, outputting the images of the first subset of images as the video image stream, moving an image sensor and/or a lens of the digital video camera from a respective normal position to a respective test position before capturing an image of a second subset of images. The digital video camera captures a second subset of images interspersed with the first subset of images, compares image quality of the first subset of images with an image of the second subset of images, and determines if the image of the second subset of images exhibits improved image quality as compared with the image of the first subset of images. If so, an image quality improvement operation is initiated.
